Following the hottest July and August on record, the earth’s rising temperature is having a number of knock on effects on rising ocean water temperatures around the world. A new study by The International Union for the Conservation of Nature has described rising ocean temperatures as “the greatest hidden challenge of our generation,” and outlined findings that indicate that ...

In order to investigate the performance of Iris wilsonii in high-salinity wastewater, seven microcosm submerged beds were built with rectangular plastic tanks and packed with marble chips and sand. Each submerged bed was transplanted with six stems of I. wilsonii. The submerged beds were operated in a 7-d batch mode in a greenhouse with artificial wastewater for three 42-d ...

“In 1986 our company used Sidel Systems to design and install a complete hot water heating system in our 135,000 sq./ft. greenhouse. The system was comprised of 51mm heating loops, headers with computer controlled mixing valves, and a 500 HP gas fires Cleaver Brooks Boiler outfitted with a matching flue gas condenser unit. Over the next 3 years we added additional greenhouse space and the ...

Today water distribution utilities are trying to improve operational efficiency through increased demand intelligence from their largest customers. Moving to prognostic operations allows utilities to optimally schedule and scale resources to meet demand more reliably and economically. Commercial greenhouses are large water consumers. In order to produce effective forecasting models for ...

Think organic farming is climate friendly? You might want to think again. A study published recently in the journal Agriculture and Human Values suggests that as organic agriculture emulates conventional industrial agriculture, the environmental benefits may not be the slam-dunk that ...

Vaccines have sparked a conversation about the need to collectively protect each other — a conversation we need to apply to environmental challenges. Ever since a small percentage of U.S. parents decided to delay or forgo vaccinating their children against diseases like measles and whooping cough — some of which have been ...

Human pressure has halved the numbers of many of the Earth’s wild creatures in just four decades, the Worldwide Fund for Nature says. While the main recorded threat to biodiversity comes from habitat loss and degradation, driven by unsustainable human consumption, it found, ...

Aggregated data reported by companies on the production, import and export of fluorinated greenhouse gases in the European Union. Background and policy The greenhouse gases (GHGs) covered by the UNFCCC Kyoto Protocol include three groups of fluorinated GHGs (the so-called 'F-gases'): hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) ...

In 2011, we wrote a column, “Global warming is happening: How should farmers respond?” (http://agpolicy.org/weekcol/549.html). In that column we began by saying, “There was a time when one could legitimately argue that there was a lack of scientific agreement over the issue of the role of humans in global warming and even whether we were in a ...

Data reported by companies on the production, import and export of fluorinated greenhouse gases in the European Union Background Greenhouse gases covered by the UNFCCC Kyoto Protocol include amongst others, three groups of fluorinated greenhouse gases (F-gases): hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6). These F-gases have ...

This work comprised of the comparative study of arsenic (As) uptake efficiency by Pteris vittata and Pityrogramma calomelanos grown in (i) As amended soils (0–600 ppm) and (ii) As tainted water (40 ppb) using a new compact continuous flow phytofiltration system in a tropical greenhouse. The As hyperaccumulation efficiency was dependent on the growth medium for the two fern ...

This article analyzes the issues that must be addressed to develop a viable sector no lose target option in the context of a post-2012 international climate regime.
